Hi Try this : using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { int[] ints = { 0 10 100 1000 1000000 }; string i =Console.ReadLine(); int num = int.Parse(i); foreach (int arr in ints ) { if (num == arr) //element found do your code here } } } }

Hi static void Main(string[] args) { int[] ints = { 0 10 100 1000 1000000 }; foreach (int arr in ints ) // change i to ints { Console.WriteLine(arr); } }

int[] ints = { 0 10 100 1000 1000000 }; string i =Console.ReadLine(); int num = int.Parse(i); foreach (int ob in ints) { if(ob == num) Console.Write(Matched); } I would recommend the simplest way of using LINQ using System.Linq; bool matched = ints.Where(d => d.Equals(num)).Any(); Plz mark it as answered if it helped you.

Hi Michael You do not need int num = int.Parse(i); and string i =Console.ReadLine(); since you are not reading user input from the console. //we declare our array here just the way you did with you 'ints' array ;) int[] intergers = { 0 10 100 1000 1000000 }; //we loop through our array 'intergers' starting from the left most value and give it a name 'i' (it could have been anything wetuumike michael etc). foreach (int i in intergers) { Console.Write ({0}  i) //we now get that value by its new name; 'i' in this case and print/display the value on the console. } Hope it helps!

hello @Micheal your code is almost correct but contain one mistake that is using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { int[] ints = { 0 10 100 1000 1000000 }; string i =Console.ReadLine(); int num = int.Parse(i); foreach (int arr in i) /* Use ints instead of i */ { Console.WriteLine(arr); } } } } as foreach (int arr in ints) { Console.WriteLine(arr); }

not sure I understand correctly but your loop shoud be foreach (int arr in ints ) { Console.WriteLine(arr); }
